Hoverlabel position on px.scattermapbox

Hi everyone,

I wonder if I can tell a hoverlabel on a plotly express scattermapbox its position relative to the datapoint it belongs to.
The reason why I need this can be see in the live dash app here: https://speichermonitor.eco-stor.de/
The hover labels for datapoints on the left/right of the map appear NEXT TO the data points with a little arrow pointing to the datapoint. However, if you hover a datapoint in the middle of the map (e.g. the red one), the hoverlabel apperas ON TOP of the data point and hides it. No little arrow pointing to the datapoint.

Is there any way to change this behaviour? Appreciate any tips/hints!
